  2. Ensure `langchain-core` is at least version `1.2.21`.

  • Added package version tracking to tracing metadata in core and partners modules.
  • Enabled validation of tool call chunks during streaming in standard tests.
  • Introduced content-block-centric streaming (v2) in the core module.
  • Added support for `base_url` alias and `XAI_API_BASE` environment variable in the xai module.
  • Added new fields to model profiles and a corresponding `Makefile` target.
  • Added `text_inputs` and `text_outputs` to model profiles.

🐛 Bug Fixes
